Here's a list of current & announced games I found.You can also go to us.playstation.com/PS3 to see other games & get links to the individual game sites.
Also once you sign up on the Playstation Network & get online there are many Blu-Ray movie previews, game demos & more all in High Definition you can download on to the hard drive of your PS3.
I've been enjoying the Gran Turismo 5 Prologue demo (& man it looks fantastic!), it's only available on the Japan store so I have several accounts (U.S, Hong Kong, UK & Japan) that way I get all the content that's out there.
All PS3 games are on Blu-Ray, while the early games looked good the latest games are really amazing.
I believe these are all PS3 exclusives, there are also many cross platform games.
